CASEMENT-WINDOW ADJ USTER.

Application filed January 8, 1917.

To all whom. t may concern.'

Be it known that we, CHARLES E. SPENCER and ROBERT C. SPENCER, Jr., citizens of the United States, residing at Chicago and River Forest, respectively, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Casement-Window Adjusters7 of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

Our invention relates to easement window adj usters and particularly to adjusters which are secured to the window sill or stool and have a mechanical connection with the inside face of the window sash.

It is one of the objects of the present invention to provide a easement window adjuster which is absolutely noiseless in operations and one which can be very easily operated, that is, one having a minimum amount of friction. With this object in view we provide an operating lever arranged to be attached to the window frame or sill having aii'outwardly extending lever or arm mechanically connected with the window sash. To produce the easy operating qualities of the adjuster and the anti-friction operating means we provide an anti-friction roller connection between the window frame and the operating lever or arm. We are aware of the fact that anti-friction roller means have been employed between an operating lever and a window frame in the past, but such constructions, so far as we are aware, have necessitated the use of specially designed window frames and window sashes, or they have necessitated drilling and similar Work on the woodwork constituting the window frame 01 the window sash or both.

It is a further object of our invention to provide an easily operated anti-friction casement window adjuster which can be applied to the window and to the frame in such a way as to avoid the necessity of doing any special work on the woodwork constituting the frame and sash.

A further object of our invention is to provide in conjunction with the above an improved locking means for locking the Win- 4dow in any position to which it may be moved, the said locking means being operated solely by the same mechanism or han- Specication of Letters Patent.l

dle device for swinging the window to any one of its several positions.

These and other objects of our invention will be more clearly brought out in connection with the accompanying drawings, in which Figure 1 is a fragmentary front elevational view of a easement window having the device of our invention mounted thereon, some of the parts being broken away in this figure to more clearly illustrate the construction of the adjuster;

Fig. 2 is a top View of Fig. 1 or a horizontal cross-sectional view of the window shown in Fig. 1;

Fig. 3 is a detail cross-sectional view of the anti-frictional connection between the operating lever and the window frame, this view being taken along the line 3-3 of Fig. 2, looking in the direction indicated by the arrows;

Fig. L is a detail view of a modified t'orm of anti-friction connection between the operating lever and the easement window sash;

Fig. 5 is a perspective view of the guide member arranged to eoperate with the friction device illustrated in Figs. 2 and l;

Fig. (5 is a view similar to Fig. 3 of a further modified form of anti-friction connection between the operating lever and the window sash;

Fig. 7 is a view similar to Fig. 2 showing the modified arrangement in which the' guide 10 forms a part of the locking mechanism for locking the window in any one of its adj usted positions; A

Fig. 8 is an enlarged fragmentary crossseetional view taken along the line 8-8 of Fig. 7 looking in the direction indicated by the arrows; and

Fig. 9 is an enlarged detail cross-sectional view taken along the line 9-9 of Fig. 7, looking in the direction indicated by the arrows.

Similar characters of reference refer to similar parts throughout the several views.

In Figs. l and 2, 7 illustrates the window jamb, 8 the stool and 9 the sill. The easement window sash 10 is hinged as shown v at 11 to the j amb 7, so as to swing outwardly as shown bythe dotted lines in Fig. 2. The

f which is attached a sleeve 16. The sleeve 16 is mounted on the rod 15 so as to have longitudinal movement relative to the rod, the sleeve being keyed to the rod in any suitable manner, so as to prevent angular movement of the sleeve relative to the rod. The lower side of the sleeve 16 carries ,a tooth or projection 17 arrangedto coperate with. any one of the several teeth 18 provided in the base 12. From the construction thus far described it will be observed that the arm 14 may be swung to any position by pulling the sleeve 16 outwardly and releasinglits projection 17 from the teeth 18, and swinging the handle 16 and thus the hub 13 together with the lever 14 to any position desired. To lock the arm 14 in any position to which it may be moved the handle 16 is again moved inwardly to cause the projection 17 to coperate and lock into one of the teeth 18. The specific construction thus far described forms no part of the present invention and we have described it merely to aid in understanding the features which constitute our invention. l

The outer end of the arm 14 carries rearwardly extending piece 19 which is rigidly attachedto the arm 14. This piece 19 extends through a slot 20 provided in the uide member 21 shown in perspective in ig. 5. The end of the piece 19 which projects into the guide member 21 as most clearly shown in Fig. 3 is provided with a steel pin 22 upon which are mounted two fiber rollers 23-23, the rollers being bev-` eled toward the piece 19 as most clearly illust-rated in Fig. 3. The guide member 21 is preferably formed of sheet metal and is bent to provide the two guiding or roller engaging faces 24-24.

To facilitate the mounting of the guide 2l on ythe window sash, the guide is provided with the apertures shown at 25--25 for the reception of screws which extend through the guide and into the woodwork forming the window sash. To close the ends of the guide the two blocks 26-26 are employed which are held in place by means of the pins shown at 27-27. The guide 21.' as most clearly shown in Figs. 1 and 2 is secured to the inside face of the window sash and the operating mechanism is mounted directly on the wlndow stool, thereby avoiding any and all cutting, -drilling or mutilation of any of the woodwork. On account of the anti-friction roller connection between the operating lever 14 andl the window frame an absolutely noiseless device and one which can be very easily operated is obtained. A further advantage yot the construction isthat the guide piece 21 or in fact any of the mechanism of the adjuster can be decorated, painted .or in any other way provided with an ornamental covering without danger of affectlng smooth running connection between the operating bracket 28' being accomplished by removal of one of the end blocks 26. K

In Fig. 6 we have shown a modification in which the operating lever 14b carries an outwardly extending piece 19b to which is journaled only one roller 23". The guideway 215 in this construction has only one outwardly extending piece or roller engaging face 24". A washer 31 is interposed be- .tween the roller 23 and the member 19", so as to providea space between the same. The piece 24h, of the guide 21b has an inwardly 'extending ledge 32 against which the underside ofthe roller 23b may rest.

`The purpose of the ledge or shoulder 32 is to prevent any possible saggingv of the outer end of the operating lever or arm 14". It is to be observed that the mechanism of our invention may be used eitherat the right hand side of the window frame or theleft hand side and that' the only work necessary to attach the device to any 'kind we find this unnecessary in viewV of the fact that the anti-friction or roller mechanism is Aentirely concealed by thel guide member. The locking mechanism constituting a art of our invention is illustrated in Figs. 8 and 9. In this construction the guide member 40 is provided with a slot extending along its front side through which the piece 41 carried by the operating lever 42 extends.

The inner end of the piece 41 has journaled 47--47 provided in the lower wall of the' guideway 40. A flat spring 48 is carried by the-piece 41 and rests against the upper wall of the guide 40, the tendency of the spring being to move the piece 41 and thus the outer end of the lever 42 downwardly with the result that the projection 46 is normally held in one of the apertures 47. The inner end of the operating lever 42 is fixed to a hub 49 which is rotatably mounted on the stud 50, as most clearly shown in Fig. 9. The stud 50 has its upper and lower ends tapering inwardly so that the hub 49 and thus the lever 42 is permitted to rock or oscillate a'bout the stud 50 when it is desired to produce such oscillation. The hub 49 is connected with, an operating handle 51 which is attached to the hub at 52 in any suitable manner, so that the handle 51 may be swung inwardly out of the way when not in use.

In opening the Window or closing it the handle 5,1 is grasped and slightly pushed downwardly with the result that the hub 49 is oscillated about the stud 50 and the outer. end of the lever 42 lifted against the tension one of the apertures the handle 61 may be" given a slight movement either in one direction or another about the stud 50; so that the projection 46 will be projected into one of the apertures.
